淤泥固化土作为工程填料使用，强度是其最主要的指标，现阶段强度研究主要集中在无侧限抗压强度及抗剪强度等参数。由于淤泥具有高含水率、富含有机质等特点，因此对淤泥固化土的强度影响因素的研究，主要集中在初始含水率、有机质、固化材料掺加量等方面。
Sludge solidified soil is used as engineering filler, and its strength is its main index. At present, the strength research mainly focuses on the parameters such as unconfined compressive strength and shear strength. Because the sludge has the characteristics of high moisture content and rich in organic matter, the research on the influencing factors of the strength of sludge solidified soil mainly focuses on the initial moisture content, organic matter, the addition amount of solidified materials and so on.
初始含水率较大，淤泥固化土强度降低；有机质大，减小固化土强度，甚至使固化材料失效;而固化材料的掺入量也是决定性因素，固化材料掺加量不足，固化土无强度，量过大，多余部分则失去作用。
The initial moisture content is large, and the strength of sludge solidified soil decreases; Large organic matter reduces the strength of solidified soil and even makes the solidified material ineffective; The amount of solidified material is also the decisive factor. The amount of solidified material is insufficient, the solidified soil has no strength, the amount is too large, and the excess part will lose its function.
